Eosinophilic oesophagitis (EoE) is now a well-recognised cause of dysphagia and food bolus obstruction (FBO). The diagnosis requires histologic confirmation, and the yield is greatest when at least 4 to 6 oesophageal biopsies are taken from different sites. Previous case reports of FBO have demonstrated a low biopsy rate, and as such cases of EoE may have been missed. In this review, the medical records of 123 patients aged 18 years or older, who had presented with FBO over a 2 year period, were reviewed. EoE was the most common diagnosis, and was found in 81.3% of patients with FBO aged 40 years or less. 45.5% of patients with FBO were biopsied, and of those, 33.9% were confirmed to have had at least 4 biopsies. EoE is a common cause of FBO and requires appropriate oesophageal sampling to confirm the diagnosis. Cases of EoE may otherwise be missed.
